There's no really other way around it unless you pay for full service. You could try other free VPNs though and see if they're faster.

One general rule is to pick the IP closest to your country so the ping would be lower (which means faster speed).

Also, I suggest you try Tunnel Bear/Hide Me/Surf Easy since according to the latest article I've seen they have wider array of IPs. This means you could change to a more suitable IP for your location.
